B'ULDING BOARD.

Application tiled may 9, 1921.

T 0 all whom, it may concern: l

Be it known that ll, HERBERT Sononrmrn, a citizen oi' the United States.residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented new and useful Improvements in Building Board,of which the following is a specification.

My invention relates to building board, and is especially designed to besecured to the frame work of a building to serve as an outside wall orsiding therefor, as well as to provide a lathing surface to which atinish coating of cement or plaster may be applied; said board being soconstructed that it may be quickly and easily applied and will form anadequate insulation from the effects of heat, cold and moisture.

Other objects will be apparent from the following description, will bepointed out in the claims and will be embodied in the accompanyingdrawings, in which:

ig. 1 represents a face view of a building board panel constructed linaccordance with my invention.

Fig. 2 is an enlarged vertical section through a portion oi the same..

Fig. 3 is an enlargement of a fragment of lFig. 2 showing more clearlycertain details of construction.

Fig. 4 is a perspective view of one of the binding members, showing itsapplication to some of the structural units which are illustrated indotted lines.

lF ig.- 5 is a view similarto Fig. 3 showing la moditiedorm of thebuilding board.

lin carrying out m invention re resents a building boar panel ci anydesired length and width, which comprises an outer wall` 11 and an innerwall 12, spaced apart and heldin such spaced relation by means of aplurality oi tie and spacing members 13.

The outer wall 10 comprises a lurali oi vertically disposed wires orros11tw ich are spaced equally apart in parallel relation and havingresting upon their outwardly disposed surfaces a metallic lathing formedof woven wire or expanded metal.

The inner wall 12 comprises-a plurality of horizontally disposed rods orwires 16 spaced apart in parallel relation, a sheetoi building paper 17disposed on one side thereof` and an outer sheet of asphaltmnl disposedon the opposite side thereof," which are secured together by a fillingof pitcho 19 interposed therebetween and encompassing said wires.

Serial No. 468,060.

The tie and spacing members 13 are preierably formed of a wire which istwisted to form a loop 2O at one of the ends through 'which the wires 16pass, a loop 21 adjacent lts opposite end through which the wires 14pass, and an intermediate spacing loop 22. The ends 28 of the wireforming the member 13 extend beyond the loop 21 and serve when twistedtogether to bind the metallic lathing 15 to the rods or wires 14E asclearly shown in the several figures of the drawing.

By the above recited construction it will be seen that l have provided abuilding board composed of two oppositely disposed wallsI spaced apart,one of said walls 12 adapted to rest against the studding of thebuilding, and being formed of insulating material, and the other wall 11being formed of ai lathing to which an outer surfacing and inishingmaterial of cementor the like, may be readily applied after the boardshave been secured in place. ln order that strength and body may be givento the board, l propose to till the space between the walls 11 and 12with plaster or cement 2d; this may be done during the process ofmanufacture of the board previous to its being applied to the buildingas shown in Figs. 1, 2 and 3 of t-he drawings; or the board may beinitially prepared as shown in F ig. 5 of the drawings and the plasteror cement filling 24 applied during the process ot applying the board,and if so desired, may be omitted entirely from the construction.

The asphaltum sheet 18 is preferably of larger area than the body of thepanel 10 and is adapted to extend beyond said body portion adyacent twooi its joining edges as shown in lFig. 1 ofthe drawings, in order thatan overlapping at the joint between the panels may be had, when they areplaced in position on the building, and the lathing material 15 is alsoarranged to overlap the body of said panel at two of its adjoining edgesfor the same purpose.

ln order that the plaster hlling 2d may be reeniorced when in a. lasticcondition. and to prevent the breaking of the panel when the paster isin such plastic condition. ll place a plurality of strips of buildingpaper 25 under each of thewires o r rods 14., thus the panels may beconveniently handled before the Jplaster has become thoroughly7 dried,without injuring the same.

What ll claim is:

1. A building board, comprising a pair titl Mib

lll@

of oppositely disposed walls, one of said walls forming a lathingsurface and the other of said walls being formed of an insulatingmaterial, means for holding said Walls together in spaced relation, anda plastic filling completely filling the space between said walls.

2. A building board, comprising a pair of oppositely disposed walls,each of said walls being composed of a plurality of wires arranged inparallel relation, the wires of one of said walls being embedded betweenan insulating material an'd the wires ofithe other wall bein providedwith a lathing surface, means iior securing said walls together inspaced relation, and a plastic filllng completely filling the spacebetween said Walls.

3. A building board, comprising a pair of oppositely disposed walls,each of said walls being composed of a plurality of wires arranged inparallel relation, the wires of one of said walls being interposedbetween sheets of-insulating material bound together, the wires of theother wall having secured thereto Aa metallic lathing, a plurality ofbinding members adapted to bind lSaid Walls together in spaced relation,and a plastic material completely filling the space be#y Y tween saidsheets for embedding said wall wires, and a plaster filling interposedbetween said walls. y

In witness that I claim the foregoing I have hereunto subscribed my namethis 15th day of April, 1921.
